N2 - Objective. To analyze anatomical and anthropometric parameters of vertebrae in children with Lenke type V idiopathic scoliosis using 3D-CT navigation. Material and Methods. The study included 15 patients aged 14-18 with thoracolumbar/lumbar idiopathic scoliosis of grades III and IV according to VD Chaklin. Anatomic and anthropometric features of the thoracic and lumbar vertebrae were assessed based on CT data in the navigation system. The total Cobb angle of the scoliotic curve, rotation of the apical and periapical vertebrae, external transverse and longitudinal diameters of the pedicles at the T2-L5 levels, and the coefficients of asymmetry of vertebral bone structures were determined. Results. The angle of scoliosis ranged from 39.8° to 84.3° (average - 59.5°), the angle of rotation of the apical vertebra - from 17.7° to 50.5° (average - 34.6°). Anatomical dimensions of the transverse and longitudinal diameters of the pedicles on the concave and convex sides at the apex of a primary curve exceeded 4.0 mm. A strong correlation between the apical vertebral rotation, the Cobb angle, and the coefficient of asymmetry of longitudinal diameters of the pedicles of the apical vertebra was revealed. The coefficient of asymmetry of pedicle areas is an integral indicator of the severity of asymmetry in scoliosis. Conclusion. A different degree of asymmetry of the bone structures of the main arch apical vertebrae was revealed in the thoracic and thoracolumbar/lumber scoliosis.
